Righty, yeah there definitely is heat conductive paint available, I just wasn't sure if it was commercially available, cheap enough for an end user and easy enough to apply to a full heatsink. If you're just retouching, then there may be something that'll work.

Me thinks replacing the white fans with anything other than other white fans would ruin the looks.

I used the interchangeable white rings then used one of the ones that came with it as an exhaust Just liked the look of the corsairs better when on the rad plus I had bought them and had them sitting for a while.
